It was a great blow to the Jedi order when Count Dooku voluntarily renounced his commission. A strong-minded man, Dooku's ideas were often out of step with those of the Jedi Council, despite the fact that his former mentor, Yoda, held a lofty position in that governing body. His challenging views were often echoed by his former Padawan, Qui-Gon Jinn, another Jedi who would on occasion defy the Council.
Dooku was a political idealist. He felt that the Jedi weakened themselves by serving an institution as corrupt as the Republic. After his departure, he disappeared for years, re-emerging as a political firebrand fanning the flames of rebellion in the galaxy. In an alarmingly short time, Dooku rallied thousands of systems to his cause, building a growing Separatist movement that threatened to split the Republic.
Opportunists working in Dooku's name would start flashpoints of violence, and it was all the Jedi could do to maintain order in these turbulent times. For all the strife, the Jedi Council refused to believe that Dooku was personally responsible for the worst of the conflicts, believing that his Jedi training elevated him above such acts.
But the Jedi didn't realize Dooku's secret. Behind a veneer of elegant charisma and well-tabled political arguments, Dooku had been corrupted by the power of the dark side. After his departure from the Jedi order, Dooku was seduced to the dark side by Darth Sidious, the Dark Lord of the Sith. By Sith tradition, Dooku adopted the name Darth Tyranus and added deceit and treachery to his already formidable array of weapons.
In both guises, Dooku began recruiting agents for what would eventually amount to the death of the Old Republic. As Tyranus, he contacted the notorious bounty hunter Jango Fett to become the template for a hidden clone army on Kamino. As Dooku, he appealed to the greed of the galaxy's most powerful commerce barons to consolidate their forces to challenge the Republic.
Deep within the mighty spires of Geonosis, Dooku chaired a meeting of the minds to formally create the Confederacy of Independent Systems. Separatist Senators alongside representatives from the Commerce Guild, the Trade Federation, the Corporate Alliance, the InterGalactic Banking Clan and the Techno Union pooled their resources together to form the largest military force in the galaxy. The Separatists were ready for war.
The Jedi Knight Obi-Wan Kenobi discovered the treasonous meeting and warned the Republic, but not without being captured. Dooku met with Kenobi in the Geonosian dungeons, and revealed to Obi-Wan the truth about the Republic -- that it was, in fact, becoming increasingly under the control of Darth Sidious. Distrusting of Dooku's words, Obi-Wan refused to believe and refused to join Dooku in rooting out the corruption.
Kenobi was soon joined by Anakin Skywalker and Padmé Amidala, who had come to Geonosis in an ill-fated attempt to rescue him. Dooku placed the three captive heroes in an execution arena, but their deaths were staved off by the timely arrival of Jedi reinforcements.
The droid armies of the Separatists engaged the Jedi, and later the newly crafted Clone Army of the Republic. Dooku attempted to escape but was intercepted by Anakin Skywalker and Obi-Wan Kenobi. The two Jedi challenged Dooku to a lightsaber duel, but Dooku's masterful skills in old-style lightsaber combat made short work of the younger combatants. As they lay wounded, another Jedi entered into Dooku's secret hangar.
The Jedi Master Yoda confronted Dooku. The two engaged in a titanic struggle of Force powers, neither besting the other. It came down to a contest of lightsabers. In a blurring tangle of speed and light, the two masters of the Force dueled. Unable to find an advantage, Dooku distracted Yoda by endangering Kenobi and Skywalker with a toppling crane. As Yoda used the Force to save his fellow Jedi, Dooku fled.
Dooku escaped, with the Jedi aware of his succumbing to the dark side, but yet still unaware of his Sith allegiance. Aboard his exotic interstellar sail ship, Dooku traveled to a decrepit warehouse district on Coruscant. There, he met with his master, Darth Sidious, and delivered the good news: the Clone Wars had begun.
For three long years, warfare ripped apart the galaxy. The Confederacy and the Republic did combat on a wide variety of planets. Military command of the droid armies fell to General Grievous, the deadly cyborg general that Dooku partially trained in the Jedi arts. Whereas Dooku handled a lightsaber with finesse and accuracy, Grievous used his bizarre mechanical anatomy to wield up to four lightsabers in a blurring haze of brutal lacerating energy.
At the end of the Clone Wars, the Separatists staged a daring strike against the Republic. The Confederacy had penetrated Coruscant's defenses and absconded away with the kidnapped Chancellor Palpatine.
It was all a ruse: Palpatine was in fact Darth Sidious, and Dooku was his apprentice. But Dooku was unaware of Palpatine's master plan. The kidnapping was a test of a prospective new Sith apprentice. Blazing onto General Grievous' flagship -- the vehicle of escape for Dooku and his "captive" -- were the Jedi heroes Obi-Wan Kenobi and Anakin Skywalker. Once again Dooku dueled with the Jedi pair. He bested Kenobi, knocking the Jedi unconscious with a brutal Force push, but was unable to overpower Skywalker. Goading the fiery-tempered young man throughout the duel, Dooku thought he had the upper hand until Anakin outmaneuvered him.
Skywalker severed both of Dooku's hands and snatched the Sith Lord's red-bladed weapon. Dooku fell to his knees before Skywalker, who was now holding two lightsabers at his throat. "Kill him," advised Palpatine -- and Dooku fully realized that treachery was the way of the Sith. He was expendable, Dooku realized. Skywalker was the true prize, the gifted apprentice, the new Sith.
This understanding awakened in him as Skywalker crossed his blades, severing Dooku's head.
